The UK P&I Club reveals its concerns about ECDIS
The UK P&I Club recently completed a series of
three short articles which provide a user friendly guide to the mystery
surrounding electronic chart display and information systems (ECDIS). These
have now been consolidated into a 16-page booklet "ECDIS - Navigational and
claims issues" that is available in hard copy from the Club or as a .pdf file
from the club's website.
While the booklet is not really intended for
navigators, it should, the Club believes, be of great value to anyone in
shipping who needs to be aware of what ECDIS is and the implications of any
ECDIS-associated errors and oversights.
All three articles can be downloaded individually or
in the 16-page combined format from the Loss Prevention section of the UK
P&I Club website
http://www.ukpandi.com/loss-prevention/lp-reports.
With the amendments to SOLAS Chapter V Regulation 19
governing the statutory introduction of ECDIS now being adopted from 1 January
2011, the 'ticking time bomb' associated with the ECDIS mandating process has
now taken on a level of greater urgency with the shipping fraternity ultimately
coming to the end of its breath holding exercise.
As with the introduction of previous mandatory
requirements to fit equipment such as Radar, VDR or AIS systems onboard
commercially operated vessels, many technical managers will now be faced with
the task of acquiring full compliance with the ECDIS carriage regulations at
the lowest possible capital expenditure. For many owners' fleets, this will be
quite complicated since not only is there is a lot of training that still needs
to be undertaken, this training needs to be type-specific. Within a fleet,
there will probably be ECDIS systems from more than one manufacturer and this
will have various implications, not the least of which will be a restriction on
which deck officers can serve on which ships.
The first LP News in this series was an
all-encompassing introduction to ECDIS and dealt with the fundamentals such as
'what is (and isn't) ECDIS?', the general training obligations relating to the
use of ECDIS as laid out under the provisions of the STCW 95 and ISM codes, the
implementation dates by ship type and size, and the attitudes of Flag States
and Port State Control. It concludes with a very valuable aid: a guide to the
acronyms associated with ECDIS.
ECDIS: an asset or a liability?
The second article in the series brings LP News and
the UK P&I Club onto home territory as it considers the operational aspects
of ECDIS and the intrinsic function that electronic chart and navigation
systems have to play in the commercially operated ship of the future.
As Karl Lumbers, a Director of Thomas Miller P&I
Ltd, Managers of the UK P&I Club, explains, the mandatory requirement and
introduction of ECDIS is seen by the regulatory bodies guiding the shipping
industry as a major step forward in safe ship operation and protection of the
environment. However, Lumbers points out that the transition to electronic
navigation and the operation of a paperless bridge is being viewed differently
by a significant part of the shipping community, which sees it meaning
increased operational costs of new equipment and additional training
requirements.
More worryingly, Lumbers points out:
"It is also becoming increasingly evident
that far from reducing risk, ineffective operation of complex ECDIS systems
resulting from poor management practices or training can actually increase the
risk of incidents such as collision and grounding with the interface between
computers extenuating the so called 'human element' reported as causative in
almost every marine casualty.
"Automation of traditional manual
navigational tasks has been observed as delaying the opportunity for error
detection and recovery, allowing a navigational single point failure to develop
undetected into a single point catastrophic failure, ultimately resulting in an
incident."
Given these facts, Lumbers believes that it is
important to highlight and publicise the importance of establishing sound and
effective ECDIS practices:
"Only by establishing such practices can an
owner expect to reap the potential benefits of ECDIS, namely the reduction of
both management costs and navigational risks."
The article then goes into much more detail than the
first did. Section headings include:
'The modern ECDIS system', which describes the
various types such as retrofits - basically standalone PCs - and integrated
bridge systems (IBS) now commonly found on newbuilds.
'Electronic charts', which addresses the
confusion that surrounds the various types of chart available and the
differences between them.
'Generic training' and 'Type specific
training', which looks at the issues surrounding effective training and what is
required to meet the mandatory requirements. Meeting the type specific
requirements is proving a logistical nightmare for those owners with different
manufacturers' products on different ships but who want their crews to be
interchangeable. Reference is made to changes in bridge management systems with
some companies adopting an airline-style 'navigator/co-navigator' arrangement.
'Passage planning' reveals the need to adopt
different procedures when using ECDIS.
Finally the article comes to:
'Risk Analysis' where the UK P&I Club
notes that given the increased technology available to the modern navigator,
one of the conundrums must be why increased computerisation and automation has
not removed, and perhaps not even reduced the potential for failure. It adds
that instead of making things safer, new pathways to failure seem to have
developed, centered on an initial miscommunication between man and machinery
resulting in a misalignment in the reality of where the navigator thinks he is
and where the automated system has actually taken him.
Research has shown that humans are poor monitors of
automated systems and tend to rely more on system alarms than manual checks
especially in relation to those systems which have proven themselves as highly
reliable. In several casualty investigations it has been determined that
automation has resulted in the navigator developing an 'operational bias'
relying on the automated systems rather than the salient cues provided visually
through the bridge window.
Lumbers concludes:
"An extensive risk assessment of ECDIS operation
combined with a clear requirement of manual system checks of critical automated
operations must be established within the company Safety Management System,
effectively identifying operational risk and introducing control measures to
reduce the effect of single point failures."
According to Lumbers, the main areas of risk when
considering ECDIS operation can be identified under three main categories:
1. The equipment itself may suffer from failure (both
hardware and software) including power outages, sensor input failure and
potential virus infection.
2. The charts are operated under permit which may
expire, charts in use not corrected up-to-date, updates not correctly applied,
ENC chart coverage unavailable, requiring the system to be used in RCDS mode
without the appropriate paper chart folio being available.
3. The operation of the ECDIS system onboard carried
out by poorly trained crew following poor navigational practices and
operational procedures such as excessive zooming or operating the chart for
navigation with base information only displayed. Effective risk assessment as a
critical function of implementation of electronic navigation is rarely
emphasised when the transfer from paper to digital navigation is
considered.
The legal implications of getting it wrong
The third article in the series, released in June, is
entitled 'Legal implications' and considers the legal effect of failure to meet
the statutory ECDIS requirements and the effect on claims where levels of
operation or knowledge of ECDIS are considered to be a factor or fundamental
link in the chain of causation leading to an incident.
Since it drills down into legal and insurance details,
reproducing it here is not practical, especially since the article is itself
quite concise despite running to over 2,400 words. However one all-important
fact should be noted above all others, says Lumbers:
"We believe that the use of ECDIS and the
management of systems associated with ECDIS will come in for great scrutiny
both by State Port Control and other regulatory bodies. Shipowners and their
crews will not only have to do things right, they must be in a position to show
that they are doing it right. Otherwise the threat of detention will never be
far away.
"Furthermore, casualty investigators will
have yet another source of information when seeking causes for incidents such
as groundings or collisions and woe betide any poor owner who can't produce
it."
Legal disputes are always likely to arise especially
when large sums are involved. The principle aim of the commercially minded
shipowner, charterer and cargo owner is of course to settle any disputes
quickly and cheaply. If however a dispute cannot be resolved between the
parties then the matter may be referred to arbitration or the courts for
determination.
The spy on the bridge
In hearing disputes between two parties, arbitrators
and judges rely upon the evidence presented to them to establish the facts of
the case. This evidence traditionally presented by the parties in the form of
both oral and written statements of witnesses and contemporary log entries and
documentation has in the past provided the basis on which to decisions have
been made.
This evidence sometimes requires the courts to
determine conflicting statements on a particular issue in dispute. To establish
the facts of the case in such situations, the judge or arbitrator has tended to
rely heavily on contemporaneous evidence such as photographic, video or
electronic information.
In this respect, electronic equipment designed with a
recording facility such as ECDIS, voyage data recorders, AIS data and even GPS
have become a crucial part of legal proceedings often used to determine
disputed facts. With literally hundreds of different types of electronic
systems with recording facilities operating different generations of software,
the recovery of this information can however be a difficult task in itself.
As this critical and at times complex procedure of
electronic data recovery has been identified, it may be questioned why many
ship managers, owners and operators have failed to provide clear instructions
relating to the preservation of such data in the event of an incident.
Critical information may be lost due to lack of
knowledge in relation to the storage space or memory of the equipment in
question or by the data being simply overwritten if action has not been taken
for its preservation. With this in mind it seems sensible for the ship manager
or owner to establish not only what electronic equipment installed on board
each vessel has recording facilities, but also provide clear instructions to
the master regarding the actions required to download the data and safeguard
this critical evidence. Failure to preserve evidence may be viewed with
suspicion and adverse inferences drawn.
It is important to understand that ECDIS systems are
capable of recording not only the log of events but the parameters of operation
set up by the operator at the time of the incident. This electronic data may
play a crucial part in the litigation process especially during the transition
period from paper to electronic navigation where questions relating to the
effective operation of ECDIS systems may be raised.
This will mean that in the case of a collision for
example where vector charts are selected and overlaid on radars having a
primary collision avoidance designation, it may be possible for the officer
charged with the navigation duties to reach information overload especially if
layers in excess of chart base levels are selected. If this ineffective mode of
ECDIS operation resulted in a target going undetected, ultimately resulting in
a collision, the failure of the navigator to act in accordance with the
Collision Regulations in this mode of operation may not only result in criminal
charges and civil negligence actions, but may render the vessel unseaworthy
with questions as to the exercise of due diligence on the part of those
responsible for the management of the ship raised by cargo interests or
insurers.

Notes to editors:
UK P&I Club
The United Kingdom Mutual Steam Ship Assurance
Association (Bermuda) Limited is generally known as the UK P&I Club. As a
mutual association, the UK Club has no outside shareholders and no financial
links with other organisations. Since its establishment in 1869, the Club has
existed solely for the benefit of its members. Its structure as a mutual
insurance association enables it to respond to the changing needs of its
assureds and allows it to provide superior service, attention and coverage.
The UK P&I Club is directed by the members.
Overall control lies with the directors, elected by the members from amongst
themselves. The directors normally meet four times a year to formulate policy
on calls, the scope of cover, finance, underwriting and claims matters,
reinsurance and issues affecting the P&I world. They resolve specific
claims which may not fall clearly within the cover.
Thomas Miller, the Club's managers, are organised to
respond promptly to requests for assistance and to provide informed advice and
help with members' claims. Individual support goes far beyond that normally
provided by a commercial insurer.
The UK Club's size and the scale of the managers'
operations has enabled the latter to develop specialist skills and expertise
seldom seen in marine P&I.
In 350 ports around the world, on-the-spot help and
local expertise is always available to members and the masters of their ships
from the Club's 460 correspondents and claims handling services and advice from
the network of offices and branches in London, Piraeus, New Jersey, San
Francisco, Hong Kong, Singapore, Tokyo, Beijing and Shanghai.
